Scintillator panel

Abstract

A scintillator panel includes a laminated scintillator having a structure obtained by repeatedly disposing a scintillator layer and a non-scintillator layer in a direction substantially parallel to an incident direction of a radiation, wherein the scintillator layer contains at least a phosphor, a binder resin, and voids, and the non-scintillator layer is transparent, and an average refractive index n1 of the binder resin and the voids of the scintillator layer and a refractive index n2 of the non-scintillator layer satisfy a relationship of formula (A) 0.9≤(n2/n1).

What is claimed is: 
     
       1. A scintillator panel comprising a laminated scintillator having a structure obtained by repeatedly disposing a scintillator layer and a non-scintillator layer in a direction substantially parallel to an incident direction of a radiation, wherein
 the scintillator layer contains at least a phosphor, a binder resin, and voids, and the non-scintillator layer is transparent, and 
 an average refractive index n1 of the binder resin and the voids of the scintillator layer and a refractive index n2 of the non-scintillator layer satisfy a relationship of formula (A) 0.9≤(n2/n1). 
 
     
     
       2. The scintillator panel according to  claim 1 , wherein the non-scintillator layer contains a transparent resin. 
     
     
       3. The scintillator panel according to  claim 1 , wherein the non-scintillator layer contains transparent fine particles in a range of 0.5 to 10% by mass together with a transparent resin. 
     
     
       4. The scintillator panel according to  claim 1 , further satisfying the following formula (B):
   0.9≤( n 2 /n 1)≤1.2.  formula (B)
 
 
     
     
       5. The scintillator panel according to  claim 1 , further comprising a photoelectric conversion sensor, wherein
 a light detection pixel (also referred to as a detector pixel, P1) formed in the photoelectric conversion sensor and a thickness (lamination pitch, P2) of a pair of scintillator layer and non-scintillator layer in a direction perpendicular to the incident direction satisfy P1>P2. 
 
     
     
       6. The scintillator panel according to  claim 1 , wherein a layer made of a light transmitting resin material is disposed between the laminated scintillator and the photoelectric conversion sensor.
